etchicsgradient: My reference to the different rating system with "its own colour for 1min bullet games without premove" is obviously exaggerated and inspired by the troll who lives there [no hyperlink here].
Although I would prefer 1min bullet games (with or without premove) to not be considered part of anybodys "true" rating. If u watch peoples live profiles its amazing how much the bullet-rating and their normal ratings diverce. Bulletrating should be like an apropo.
This is a very interesting discussion. I don't feel strongly about pre-moves, as I never play bullet. However, I must express my horror at adding a fourth rating.
First of all, a newcomer is very confused by the difference between live and on-line, and the three different ratings in live (questions "why did my [standard] rating not change when I won a [bullet] game"? are on a daily basis, and almost every friend to whom I've shown chess.com had the same question).
More importantly, a rating is more accurate if the player plays more games. If there were two separate rating systems (premove, no-premove), players who'd play both types of games (either they have no preference, or they didn't find a seek that'd match theirs) would wind up with two ratings, both less accurate than the current unified rating.
However, the change itself sounds very reasonable-premoves, are afterall, a bit of a variant. So I'm all for making them optional, but please... no fourth rating!
